Thanks I didn't know they could go for months. There is an excellent thread, in here, that shows the different stages of shedding and I've been watching for signs but so far nothing. I thought she might be getting ready about a month ago but other then looking a bit dull she never developed any of the symptoms.
I have a baby corn snake that sheds consistently every month and the signs are very obvious when it starts but not with Baloo. It's amazing how different they are.
